U 200x75x4.25
BR — Cold-formed Channel
Cold-formed channels (U shapes) are similar to C shapes but without stiffening lips. Used for light structural framing, supports, and secondary members.
Also known as: U 200x75x4.25 (UK / Australia)
The U 200x75x4.25 steel profile weighs 11.1 kg/m (7.49 lb/ft), has a depth of 200 mm (7.87 in), flange width 75 mm (2.95 in). Cross-sectional area: 1,433.3 mm². Moment of inertia Ix = 841.83 cm⁴, Iy = 68.89 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 4.25 mm ≈ 8 gauge (Manufacturers Standard Gage)
